Trained first aider Vikki Cave went to help Fusilier Lee Rigby when she saw him lying on the Woolwich street and called the police.

Speaking to ITV News UK Editor Lucy Manning, she said: "It was a natural reaction to go and help and I didn't realise that they [Lee Rigby's killers] were there and when I did realise, that was a bit of 'Oh my god, it’s kind of scary’, especially when I saw the gun."

Ms Cave said a woman who was sitting beside the soldier rubbing his back was "so, so brave, absolutely amazing. If that was my son I'd want someone to be there. She was incredible."

"I spoke to the man and said: 'Is she ok, are we safe, are you going to hurt us?' And he said the women and children are safe but when your police and soldiers get here you need to back off as I can't guarantee anything."

Earlier this month the jury was shown footage filmed on a mobile phone of Michael Adebolajo, one of the men found guilty of murdering soldier Lee Rigby, attempting to justify his actions shortly after the killing.
